Gas & Explosive Warning Signs: Buying Guide


If you work in an industry where gas and explosions are potential hazards, you will be well aware of the need to protect employees and visitors from the harm that they can inflict. Gas and explosive signs can be used to make sure that areas at risk of gas and explosions are clearly labelled to protect everyone on your premises from injuries or even death.

There are a number of options in our range of gas and explosive signs to best suit your requirements, including a choice of material. Choose rigid plastic for a durable sign that is suitable for both indoor and outdoor use, or vinyl, which can be attached to most smooth, clean surfaces but is particularly ideal for curved surfaces such as gas cylinders. See our guide to signs materials for more information on these and other materials available. Don't forget, some signs will require specific sign fixings depending on the size, style and location of use.

All of our signs feature the well-known hazard triangle with the relevant gas or explosion symbol. Some include the letters EX in the triangle to show that an explosive atmosphere is present at the corresponding ATEX category.

Others simply feature the easily recognisable explosion symbol.

For gas cylinder storage areas consider using signs that display the image of an exploding cylinder.

One of the biggest dangers in an area at risk of gas and explosions is that of fire, which could be triggered by smoking of cigarettes or the presence of naked flames. Make sure that everyone knows not to smoke or have naked flames in these areas by using the appropriate prohibition sign.

Gas and explosions may remain a risk, but with good management, the risk is very low. Displaying gas and explosive signs in the appropriate locations in your business premises will prove to everyone that the risk is being well managed and will help prevent accidents as part of your health and safety policy.

No Room for Complacency on Explosive Signs


Sites where explosions and gas leaks are potentially possible have become much safer thanks to legislation and rigorous trade standards on this topic. Yet evidence suggests that the rate of UK gas explosions doubled in five years to 2021. Those figures include both residential and workplace incidents.

This adds urgency to the need to source compliant gas and explosive signage.

Who Uses an Explosive Sign Supplier?


There are workplaces where the risk of an explosion is obvious, such as quarries, demolition companies, factories producing chemicals, laboratories and any kind of mining operation, including gas and oil rigs.

However, it is not just these companies that need explosive signage, as many other workplaces store flammable substances or explosive gases on their premises.

Facilities managers may need to consider storage of large amounts of cleaning supplies, for example, as this may also be a recommended location for an explosive hazard sign.

Healthcare providers that store oxygen supplies are also mandated to use recommended explosive signage, and in particular a compressed oxygen sign to indicate where extra care is needed.

Agricultural enterprises are another type of worksite that needs to be vigilant in using risk of explosion signs – for example, danger propane signs for buildings heated by this gas to house livestock and horticulture.

Best Practice Tips for Explosive Signage


It all starts with a thorough risk assessment of your site and mapping out exactly where Control of Substances Hazardous to Health (COSHH) rules apply, or there is an additional risk of explosion due to leaks and spills.

This should take into account not just locations with a clear requirement for an explosive sign, such as storage rooms and cabinets. Look for places where hazardous substances are used, or transferred from tanks to equipment, for example.

Do your consignments of gas tanks and potentially explosive materials get unloaded at a particular part of your warehouse? Gas & explosive signs could be important there, alongside your informational safety signage on how to handle these inventory items properly.

Even somewhere such as a laboratory may need to consider erecting a danger explosive atmosphere sign where volatile chemicals are temporarily stored or used.

The trick is to source a range of different safety signs that manage explosive risks, and preferably ones that are versatile enough to fit to various surfaces.

If you need signage that communicates risk quickly, or for non-English speakers, make sure that you use the universally accepted risk of explosion symbol on your hi-vis safety signs.

Staff training and risk of explosion signs

One of the key factors in keeping your employees safe if they work in environments where explosive signage is the norm is to make sure that they take the risks involved seriously on a daily basis.

For example, this may demand regular refreshers on why an explosive hazard sign is needed, and what to do if they have concerns or spot a procedural problem. Do they know the indications that an explosion is possible, such as the smell of sulphur, or hissing or whistling sounds near gas?

How do they check storage arrangements for potentially explosive materials and ensure that your danger of explosion sign hasn’t been obscured by racking and other inventory?

Thorough training and reminders on this topic – along with your gas & explosive signs – help to keep your staff, visitors and contractors safe, and protect your business premises, equipment and productivity.
